Static Transfer Switch
Our Static Transfer Switch transfers seamlessly loads from one source to the other.
Fully solid-state, the iSTS includes smart features for optimum switching between asynchronous supplies and transfer of inductive and non-linear loads.
If a load is faulty, the transfer will be halt till its cleared to avoid propagation of a current fault to the alternate source.
If the fault is not cleared, iSTS protections will be actioned: the load and/or all loads connected to the iSTS will not be supplied.
Static transfer switches can be used where reliable and independent sources of power are available, and it is necessary to protect the load from even a few power frequency cycles interruption time, or from any surges or sags in the prime power source.
They enable flexible site maintenance ensuring high availability.
